Write a function "add_together" that consumes two integer parameters and returns their sum. Call the function once, and then print the result.

a) "def add_together(a, b) : return a plus b; print add_together open parenthesis 5 comma 7 close parenthesis"
b) "def add_together(a, b) : return a times b; print add_together open parenthesis 5 comma 7 close parenthesis"
c) "def add_together(a, b) : return a divided by b; print add_together open parenthesis 5 comma 7 close parenthesis"
d) "def add_together(a, b) : return a minus b; print add_together open parenthesis 5 comma 7 close parenthesis"
